Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple tent assembly frame that has been improved so as to simplify assembly work.

It can be used as the headquarters for sports days, groundbreaking ceremonies and construction sites, temporary headquarters for government offices and police, work rest areas in fields, stalls and mock shops for garden parties, first aid stations and temporary shelters in disaster areas, etc. Simple tents are widely used for lodging.

This simple tent has pillars as shown in Figures 1 and 2.
It was equipped with pipes as pillars, pipes as beams, pipes as ridges, pipes as girders, and various small pipes, and these various types of pipes were connected to each other (assembled by tying them together).

However, this is quite complicated as it requires various pipes such as pipes for columns, pipes for beams, pipes for ridges, pipes for girders, etc., and the length of these pipes varies depending on the type of pipe. differ greatly.

Assembling the tent frame was therefore difficult and required at least two workers, and in some cases more.

Furthermore, even the slightest mistake in connecting the pipes would make assembly impossible, so a great deal of care had to be taken when connecting the pipes.

Also, since the size of a simple tent is fixed, once you purchase a large tent (if you only need to install a small main seat etc.), you will have to install a small main seat etc. in a large tent, creating dead space. There were so many that it looked bad.

Furthermore, if it becomes necessary to set up a simple tent on a narrow piece of land, it is not possible to erect a large tent on that narrow piece of land, so a new small tent must be purchased, which is uneconomical. Ta.

That is, the size of the conventional simple tent is fixed, and since the structure is not such that a plurality of tent frames of the same size are connected together, it is inconvenient that the size of the simple tent cannot be changed.

The present invention was made in view of the actual situation of conventional simple tents, and its purpose is to simplify the structure of the tent frame, and at the same time, to integrate multiple tent frames of the same size into one unit. By connecting the tent to the tent, it is possible to change the size of the simple tent depending on the headquarters, land conditions, etc.

Another object of the present invention is to make it possible to easily assemble and disassemble tent frames of this type, and also to enable each tent frame to be firmly connected.

Incidentally, there is a device similar to the present invention in Japanese Utility Model Publication No. 306548.

As described in the publication, the pillar and beam are simply connected in one piece to save the trouble of attaching and detaching, and the connected portion is constructed to be foldable.

Therefore, in the case of Utility Model Publication No. 30-6548, it does not have the purpose of connecting a plurality of tent frames into one body, and of course, it does not have a structure in which tent frames can be connected.

The present invention will be specifically explained below with reference to the drawings.

The main features of the present invention over the prior art are that it has a structure that can be separated into pillars and beams, that it has a tent frame with a square plane, and that it uses square pipes.

The reason why we decided to disassemble the tent into pillars and beams is to connect multiple tent frames into one unit, as mentioned above.

The reason for using square pipes is to ensure strength with a small amount of pipes.

FIG. 3 is an enlarged perspective view of a unit tent frame having a square plane, and FIG. 6 is a plan view of the tent frame.
FIG. 7 is a front view.

As is clear from Figure 6, the length of one side of this tent frame is Ll.
and the length L2 of the adjacent side were considered to be homogeneous.

That is, the plane is made to form a square.

In this way, since the tent frame is a single unit with a square plane, the pipes that are the constituent elements of the tent frame, that is, the four straight square pipes 1.2 used as the pillars of the tent frame.
, 3 and 4 are made equal in length and shape.

In addition, the lengths and shapes of the four square pipes 5, 6, 7, and 8 used as beams of the tent frame extending from the upper ends of the square pipes 1, 2, 3, and 4 in the upright state to the center of the square are also equal. ing.

4 straight square pipes used as tent frame pillars 1
, 2, 3, and 4 are erected at the corners of the square.

These square pipes 1.2, 3, and 4 are hollow inside, and in the case of the example shown in the drawing, as is clear from FIG. It is said that

Four square pipes used as beams of the tent frame 5.6,
7 and 8 are lower end portions 5a, 6a, ? a and 8a are curved.

The reason for the curved shape is that it was designed to fit into the vertical square pipes L2 and 3.4.

That is, the lower end portions 5a, 6a, 7a, 8a are bent or
Square pipes 1, 2, 3, 4 with this curved part in an upright state
Since it will fit into the upper end of the square pipe 5, 6, 7, 8,
It can be tilted as shown in the figure and can act as a beam.

Therefore, in the present invention, the tips of the curved portions of the square pipes 5, 6, 7, 8 and the upper ends of the straight square pipes 1, 2, 3, 4 are fitted together and fixed with pins 9, for example. There is.

In Fig. 4, 10 is a beam connector, which has square projections 11, 12, 13, and 14 pointing toward the square corners.
have.

The square projections 11, 12, 13, and 14 are provided to project obliquely downward at an angle of 90 degrees, respectively, so as to be directed toward the corners of the square.

This beam connector 10 is provided with a square center f as shown in FIGS. 3, 6, and 7, and four square pipes 5, 6, 7, and 8 as beams are connected to the square protrusion 11°. 12.13,14
It fits into the square and connects at the center of the square.

In the case of this beam connector 10 shown in FIG. Act 19 (Fig. 7) This act tenses or loosens the tension.

As described above, in the present invention, the tent frame is a single unit with a square plane, and the square pipes 1, 2, 3, .
Since the lengths of 4 are equal and similarly straight, and the lengths of square pipes 5, 6, 7, and 8 as beams are equal and have similar shapes,
When assembling the tent frame, use the corners as pillars] 9b1.2,3,
Any of the square pipes 5, 6, 7, and 8 serving as beams may be connected to any of the square pipes 4.

That is, in FIG. 3, a square pipe 1 as a pillar, a square pipe 5 as a beam, a square pipe 2 and a square vibro,
square pipe 3 and square pipe 7, square pipe 4 and square pipe 8
However, instead of this, the square pipe 1 serving as the pillar may be connected to any of the square vibros 7.8 as the remaining beams.

Similarly, the square pipe 2 as a beam may be connected to any of the remaining square pipes 7.8°5 as beams.

The same applies to the other corner vibrators 3 and 4.

Since any beam pipe can be connected to any column pipe in this way, unlike the conventional method shown in FIGS. 1 and 2, care is not required during assembly and the assembly work is simple.

In addition, it is desirable to have a connectable structure in which a plurality of tent frames are connected together, and to make the structure as simple as possible in order to save time and effort in connection.

In the case of the present invention, since square pipes are used, strength can be ensured with a small amount of pipes, and the effect of eliminating the need for reinforcing pipes such as girder pipes as in the past can be achieved.

This is also clear from a comparison between FIGS. 1 and 2 (however, they are scaled-down views) and FIG. 3.

Also, since it uses a square pipe-to-square pipe fitting method,
The pipes do not spin idly in the fitted state, and therefore no special idling prevention member is required.

Incidentally, as shown in FIG. 8, a horizontal plate 21 for laterally extending the tent base 20 may be provided between the square pipes serving as pillars.

The horizontal plate 21 is installed by inserting the tongue piece 21a at the tip of the horizontal plate 21 into the gap between the stopper 22 and the square pipes 5, 6, 7, and 8, as shown in FIG. There is.

The main feature of the present invention is that it has a structure in which pillars and beams can be disassembled and the plane is square, and that one unit of tent frame can be constructed by sequentially connecting it to lateral forces. be.

Although the state in which two tent frames T are connected is shown in FIGS. 9 to 11, the present invention is not limited to this, and three, four or more tent frames T may be connected as shown in FIG. 14A. good.

In this case as well, straight square pipes 1 and 2 having the same structure as described above,
3, 4, square pipes 5, 6° 7.8 as beams, beam connectors 10 are provided, and a joint 23 for connecting one unit of tent frame T and one unit of tent frame T is provided. It is being

As shown in FIG. 12, the joint 23 has a plurality of, for example, two square projections 24, 24 directed upward.

This joint 23 has a square pipe 2 with its own square hole 25 as a pillar.
FIG. 13 is a perspective view of the state before the joint 23 is connected to the upper end, and FIG. 13 is a perspective view of the state after the joint 23 is connected to the upper end of the square pipe 2 as a column.

This joint 23 is used to firmly connect one unit of tent frame T and the adjacent unit of tent frame T connected to it, as shown in FIGS. 9, 10, and 11. It is something that

That is, this joint 23 is a connection point between one unit of tent frame T and an adjacent unit of tent frame T connected to it.
It is fitted into the upper ends of square pipes 2 and 3 as pillars.

11 (as shown, a square vibro 5 is firmly connected to one joint 23a, and the other joint 23b
A square pipe 7.8 is firmly connected to.

As described above, one unit of tent frame with a square plane is firmly connected to the lateral force in order by the joint 23, and in the case of two tent frames, or three or four tent frames as shown in Fig. 14, If more connections are made, the overall size of the tent frame can be gradually increased.

Therefore, the tent frame of the simple tent can be made variously large depending on the size of the sports day, groundbreaking ceremony, headquarters seat at a construction site, etc., and the thicker the tent, the more practical it is.

Furthermore, if you only need a small main seat, or if you want to set up a simple tent on a narrow plot of land, you can disconnect the connections and use it as a small tent frame, so there is no need to purchase a new small tent, making it more economical. There is sex.

Of course, as described above, the assembly and disassembly work is simple.

Furthermore, it goes without saying that the tent frames T may be connected not only in the left-right direction as shown in FIG. 14A, but also in the front-back direction as shown in FIG. 14B1.

This is because the tent frame is square and has no directionality.

Furthermore, if three square protrusions 24 are provided on the joint 23, the tent frame T can be firmly connected in an L-shape as shown in FIG. It is convenient because it can be connected in various shapes depending on the needs.
